lrim the 'retainingy ring 21 ma and 4 I have shown a sectional demountable Ifm.v Referring first to the construction in- 4volving the continuous tread the rubber tread -5 1s received between two ,retaining rings 21 and 22, which encircle the demountable r'iini4 andare detachably secured theretachably secured tothe demountable tread by v'means of screws 26. T27 designates twistedwires or rods which .are embedded inthe tread 5and extend through and are welded to the ring 24, the ends of-said rods projecting beyond .the base portion of the tread and entering recesses 28 formed in the retaining rings 21, 22. The rods or- Wires 27 and the ring24 'will be incorporated in the tread portion while the latter is being made, as seen in Fig. 7. f

In assembling the tire and demountable curedt'o the deinoiintable rim y the screws 23' and then the rubber tread' 5 may be put in place .with the ends of the Wires 27 entering the recesses 28 in the ring 21, and after' the tire is secured in place by inserting theA screw'sf 26 the other retaining ring 22 is put.

into place with the ends of the rods 27 entenv ing the recesses, 28 therein. Said ring 22 vis. then secured'in place by the screws 23. Thev tread 5 and demountable rim are thus .firmlyL secured together and may be appliedto the"i between-Which thetread section 50 is reoeii'fed,;said retaining ring sections being sewh'eeland then clamped in place thereon by f' the clamping ringv 7 and locking ring 16.

It will be noted that inthe above con- Each vtr'ead'fsectio'n v50 also has embedded struction the screws 23 andv 263Which secure thefretaining rings and the ring 24to the demou'ntable rime are inserted lfrom the 1ntei-,lor of the said rini, and moreover that the Wiresor rods 27 fare situated a sutlicient distance from the intcriorface of the tread so that they have a lirin'holdtherein.

I prefer l'to make the rubber tread 5 with the grooves 29 in which the retaining rings 21 and 22v are received, so that the outer edges of said retaining rings come substantially flush with. the sides of the tread'. I also preferably make' the positioningring and the clamping ring 7 of suiiicient size so that the outer edges thereof will overly the.

retaining rings 21.and 22 and extend somewhat beyond said Figs. 2 and 5. The particular size ofthe positioning and clamping rings, however, is not essential to the invention.

In Fig.' 8 'I have shown an embodiment Where the positioning ring 6n not only; ex-

tends beyond the retaining rings 21 and 22, but is formed at its outer edge with the inwardly-bent iange 31 which enters an anrst bese.. v

Where the sectional con struction is employed I will preferably make the demountable rim vwith the saine number of sections as there larein the rubber tread so that each tread vsection,end hits demountable rim section constitute an entity which can be removed from the Wheel Without disturbing any of the other sections.y In Fig. 4, for instance,- tlie tread sections are riesig- 'natedby 50 and the demountable rim sectionsv by `vi0; The demountable rim sections are arranged end to end so that when they are in place they constitute a complete demountable rim. I will preferably so place these demountable rim sections 40 on the vtire so ythatthe ends thereofwill rest on the 1'bolts 9,' and the bolts 9, therefore, will jsup- 'Y port the meeting ends of two adjacent rim Sections:A Each tread "section 50-is secured to its rim section by means similar to that illustrated .in' Figs. `2 and 5, that is, each tread section-has embedded therein Aa length 'of wire 2450 Whichiis vsecured to the rim sec` tionO by screw's V o r bolts 2 6 and each deinountablerim section 40 has secured thereto two'fclamping ring sections 210aiid 220 curedjtothe: rim section 40 bv screws 23.
